THE

Specification of Letters Patent.

Patented. Dec. 12, 1905.

Application filed December 10, 1904. Serial No. 236,344.

To all whom it may concern.-

Be it known that I, JOHN AUGUSTUS HIoKs, a citizen of the United States,residing at Summit, Union county, New Jersey, have invented certain newand useful Improvements in Means for Sealing Vessels, of which thefollowing is a specification.

My invention relates to sealing means for vessels; and it consists incertain elements fully specified and claimed hereinafter.

In order that those skilled in the art to which my invention appertainsmay understand, construct, and use my invention, I will proceed todescribe it, referring to the drawings herewith forming a part of thisspecification.

Figure 1 is a longitudinal elevation of my invention, showing thesealing-cap on a bottle. Fig. 2 is an elevation of the top of a bottlewithout the cap and showing the lugs upon the top of the exterior of theneck, the under side of which lugs is parallel with the top walls of thebottle. Fig. 3 is a topview of the same. Fig. 4 is a longitudinalcentral section of the bottle, showing the cap on the bottle, theindents in the cap which lock the cap on the bottle, also showing ashoulder in the bore of the bottle-neck near its top, and a stoppercompressed between the top surface of the cap and the shoulder inthe.bore of the bottle, also the top edge of the stopper compressed intothe crack or space between the top surface of the cap and the top of thewalls of the bottle. Fig. 5 is a reversed view of the cap or a view ofthe under side thereof, showing the indents in the cap and the stop.Fig. 6 is atop view of Fig. 7. Fig. 7 is a vertical central section of abottle-neck, showing a taper mouth instead of a shoulder in the mouthand for the same purpose.

A is the body of the bottle.

B is a swell near the top of the bottle-neck.

C is the top surface of the cap.

C represents indents in flange E.

D is an indent in the pendent flange E.

E is a flange pendent from the outer diameter of upper surface 0 of thecap.

F is a stopper of compressible material located in the mouth of thebottle and resting on the shoulder G. I

G is the bore of the bottle belowthe shoulder Gr.

G is a shoulder near the top of the bore of the bottle-mouth.

H is the outer diameter of the bottle-neck above the swellB and belowthe lug or lugs I.

I represents lugs formed at-or near the top of the exterior of the neckof the bottle.

In both forms of locking the cap to the bottle-neck the contents of thevessel when under pressure from Within the bottle forces the top edge ofthe stopperagainst the under flat side of the cap and into the crackbetween the cap and bottle, be it small or large, and insures a tightseal, the stronger the pressure the better the seal will be.

The method of locking the cap to the bottle (shown in Figs. 6 and 7) issimilar to that shown in patent to James M. Hicks, December 8, 1903, No.748,329, the stop-indents in the cap taking against the vertical sidesof the lug on the bottle in looking and unlocking the cap to and fromthe bottle by parallel and circumferential movement only.

The operation of my invention is as follows: The bottle being chargedwith fluid, the stopper F is placed in the mouth of the'bottle, the topof the stopper protruding slightly above the top of the walls of thebottle-mouth. The cap 0 is then placed upon the bottle and pressed downto compress the stopper F until the indents O reach below the level ofthe lug or lugs I, thus compressing the stopper to the level of the topof the walls of the bottlemouth, as near as may be practical, leaving ofcourse a slight crack or space between the two into which the compressedstopper will be forced more or less diametrically. The cap is thenturned, bringing the indents C under the lugs I until the stop D strikesthe edge of a lug and limits the circumferential movement. To' open thebottle, of course the cap is turned in the reverse direction until thestop D strikes the reverse side of a lug I, and the cap is then liftedupward and off, or, in case the bottle is filled with pressure, it willbe forced ofl with the, stopper F.

The greater the pressure in the bottle the more will the stopper beforced diametrically into the crack between the cap G and the top of thevessel walls, thus securing a tight closure.

Having now fully described my invention and the manner in which I haveembodied it, what I claim as new and as my invention, and desire tosecure by Letters Patent, is-

l. A sealing-cap for vessels, comprising a top surface; a flange pendentfrom said top surface provided with horizontal indents near its loweredge and substantially parallel with the said top surface, to lock it toa vesselneck; a stop-indent located slightly above the horizontal lineofthe said horizontal lock-ingindents, all constructed, arranged andcombined, vwhen on a vessel to lock the cap to it, by taking under a lugor lugs thereon, and to limit its circumferential movement by takingagainst the vertical side of a lug, substantially as specified.

2. In a means for sealing vessels, the combination consisting .of asealing-cap having a top surface; a flange pendent fromsaid top.

mouth having a contraction located within said mouth forming a detent, astopper compressible between the under surfaceofthe top of the cap andsaid \detent located within the vessel-mouth, and into thes-pace betweenthe under surface of the cap and the walls of. the

vessel-mouth, substantially as specified.

In testimony whereof I have signed my .name to this speoificatiomin thepresence of twosubscribing witnesses, this 29th day of November, 1904:.

JOHN AUGUSTUS HICKS.
